Unlike modern "Merged" sets, this set is typically distributed as Non-Merged
, meaning each ZIP file contains every file needed to run that specific game without needing a "parent" ROM. Why Version 0.37b5?
In the world of emulation, "newer" isn't always "better" for every device. Modern MAME versions prioritize

Unleashing Retro Power: The MAME4ALL 0.37b5 Complete Romset (2270 Games) For retro gaming enthusiasts, the MAME4ALL 0.37b5 2270 Complete Romset
is often considered the "sweet spot" for performance and compatibility. While modern MAME versions focus on extreme accuracy, they often require significant hardware power. In contrast, the 0.37b5 set is optimized for lower-end devices like the Raspberry Pi, early Android phones, and handhelds like the RG350. What is the MAME4ALL 0.37b5 Set?
This specific collection is built around the MAME 0.37b5 core, which originally debuted in July 2000. It is a curated selection of approximately 2,270 romsets—hence the "2270" in the name—designed to run efficiently on mobile and ARM-based architectures.
Emulator Compatibility: This set is the required standard for the popular MAME4droid (0.37b5) on Google Play and the MAME 2000 core in RetroArch.
Performance: Because it uses an older, less demanding core, it allows classic titles like Pac-Man, Galaga, and Street Fighter II to run at full speed even on modest hardware. Even with a complete set, issues arise
Completeness: A "complete" set typically refers to having all parent ROMs and necessary clones available in this specific version's format. You can verify your files against the mame4all gamelist on GitHub to ensure you have the right titles. Why the "2270" Version?
The number 2270 comes from the official count of unique romsets supported by the MAME4ALL_Pi project on RetroPie. While modern MAME sets now include tens of thousands of files, this lean 2,270-game collection focuses on the "golden age" of arcade gaming, stripping away the non-working or overly complex 3D titles that wouldn't run on mobile hardware anyway. Setting Up Your Romset
Download the Correct Version: Ensure your ROMs are specifically labeled for 0.37b5. Newer ROMs for current MAME versions (like 0.250+) generally will not work because file names and structures have changed over decades of development.
Use a DAT File: To verify your set, use a "DAT file" with a ROM manager like ClrMame Pro. This ensures every zip file contains the exact files the emulator expects.
Place the Files: On Android, for example, zipped ROMs are typically placed in the /sdcard/ROMs/MAME4all/roms folder. Summary of Key Features
Optimized for: Raspberry Pi, Handhelds (RG350, Miyoo Mini), and Android. Game Count: 2,270 unique arcade romsets.

The "MAME4ALL" variant tweaked the audio and input latency specifically for portable Linux devices, Dingux, and the RetroFW platform.
It is the definitive "throw it on a card and forget about it" ROMset.
